CVE-2021-33203Network attack vector

Staff-only arbitrary file probing via unsanitized template path

Published Jun 8, 2021 · Updated Aug 3, 2024

Path traversal in Django before 2.2.24, 3.0 through 3.1.11, and 3.2 through 3.2.3 allows remote authenticated users to probe files. TemplateDetailView joins a URL-supplied template path to each configured template directory without validating that the result remains inside that directory. Staff access to admindocs is required, and file contents are exposed only when application developers customize the admindocs templates to display them.
